ABSTRACT:
A pothole patching and roadway surface repair and paving machine is described having a mobile chassis frame mounted on wheels for transport over a roadway. The machine is formed with an elongate boom mounted on the frame at an upwardly directed angle with the lower end of the boom formed with an opening position for receiving repair material dispensed from a source. The boom is constructed and arranged with a boom conveyor extending internally the length of the boom for conveying repair material dispensed from the source to the top of the boom. The boom is mounted on the frame for movement right and left over a roadway surface on a vertical pivot axis and for movement of the boom up and down on a horizontal pivot axis for varying the upwardly directed angle of the boom. An elongate chute or hollow stick is pivotally mounted to the upper end of the boom at a downwardly directed angle. The chute is pivotally mounted for varying the downwardly directed angle relative to the boom and is arranged to receive repair material conveyed to the top of the boom and drop the repair material through the chute to selected locations on the ground. A roller assembly is coupled to the lower end of the chute for rolling repair material dispensed from a source via the boom and chute to the selected locations on the roadway surface. Operator controls are provided for control of independent degrees of motion of the various elements of the machine.
